How do I highlight the complete Radio element, label and checkbox, when the user checks on a Radio box? Is there a way to do this?

It would like to make it very clear to the user which selection he has chosen and the checkmarks are not enough, especially on the ipad since its bigger screen might mean that some checkmarks are far away (on the right of the screen) from their labels (on the left).

I thought about using the 'check' event on the Radio but the problem is that a Radio only generates a 'check' event, and not an 'uncheck' events. So, if the user changes his mind and changes his choice I would have to somehow un-highlight the first choice.
